Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of seams along the center lines of plugs at the removal of a tungsten film by specifying the film forming condition at the formation the tungsten film over the whole surface of a substrate by the CVD method. SOLUTION: After a base oxide film 1 is formed on a semiconductor substrate, an Al wiring 2 is formed on the film 1 and an interlayer insulating film 3 is formed over the whole surface of the substrate and planarized. Then through-holes 4 are formed to the Al wiring 2 through the insulating film 3, and a barrier layer is formed by forming a TiN film over the whole surface of the substrate including the internal surface of the holes 4. Successively, the holes 4 are filled by thinly growing tungsten crystallites on the internal surfaces of the holes 4 and forming a CVD tungsten film over the whole surface of the substrate. At the formation the tungsten film, a temperature T of the substrate and a pressure P in the film forming chamber are respectively adjusted to T>475 deg.C and 90<P<=150 Torr, so that the film may become a high-density tungsten film 5.  Then the tungsten film 5 is removed from the surface of the substrate by the CMP method, and an Al wiring 6 is laid on obtained tungsten plugs 9.

IPC: F16F9/46
Filed: 1986-10-06
Abstract: PURPOSE:To improve the durability of a shock absorber by separating the adjusting mechanism of a shock absorber and its electric driving means through a separating means formed of non-magnetic material, and magnetically coupling them. CONSTITUTION:The valve body 201 of a rotary valve to adjust the damping force of a shock absorber is supported by a rod 162, and permanent magnets 158a, 158b are fixed to said valve body 201. Permanent magnets 155, 156 are fixed to a magnet holder 154 attached to the shaft of an electric motor 151. The driving force of the electric motor 151 is transmitted from the permanent magnets 158a, 158b to the permanent magnets 155, 156 through a cap 157 formed of non-magnetic material. Thus a sealing means becomes unnecessary, and thereby the durability of a shock absorber can be improved.

Title: Nonvolatile semiconductor storage
Inventor: NOGUCHI KENJI
IPC: G11C16/06
Filed: 1992-08-12
Abstract: PURPOSE:To eliminate excess writing, erasing by omitting writing of writing to erasing of an auto erasing function when all bit '0' is decided in a data block. CONSTITUTION:When an output 29 of all '1' deciding latch 8b is an H level, data ''0'' is written at the time of writing all '0' to reading as usual in the case of auto erasing, but even in this case, if an output of the latch 8b is an L level, writing is not executed. An erasing circuit does not output a high potential to a source line, and does not erase in the block. Thus, the output 29 of the latch 8b skips all '0' writing to erasing cycle at the time of an L level. When an output 40 of all '0' deciding latch 8a is an H level, a writing circuit writes ''0'' at the time of writing cycle in the case of the auto erasing, but does not write even in the case of all '0' writing cycle at the time of L level, and erasing is merely executed.
